Centering

Upload a card image, place the guides on the border edges, and check front and back centering with live results for Pokemon cards, sports cards, and other trading cards.

For final alignment, the loupe can show a suggested edge assist when you are close to a likely border at 1.25x zoom or higher. It is meant to help you fine-tune the guide, not override your judgment.

What Kind of Photo Should I Upload?

Use a clear, flat picture of the full card and try to fill as much of the image as possible with the card. If you use Take Photo, the built-in camera template helps with framing.

How to Get an Accurate Measurement

To get the most accurate measurement, make sure the card fills most of the picture. If the angle is off, just use the perspective button to help flatten it. Zooming in can help you line the guides up as close to the border as possible, and the auto loupe is great for a final check.

After placing the guides, inspect the full border and make sure each guide still matches the widest visible part of that border, not just one small section.

When Should I Use Image Adjustment?

Use Perspective when the card looks tilted, trapezoidal, or slightly rotated in the photo. Place the four corner brackets on the card corners first, then use Straighten if you need to level the top or side borders. When you apply the correction, the tool keeps a small safety margin around those corners so a tiny placement miss is less likely to cut into the card border.

Use Crop Only when you just want to trim the image without warping the card. In that mode, drag the crop edges to tighten the frame around the card.

After the first pass, recheck everything before you apply. Straightening or tightening the crop can shift the framing slightly, so it is worth confirming one more time.

What Is the Suggested Edge Assist?

The suggested edge assist is the guide line that can appear inside the loupe while you drag a guide at 1.25x zoom or higher. Think of it as a final alignment helper, not an automatic measurement.

It works best when there is a strong visual difference between the border and the card image, such as:

  • a bright yellow border against darker artwork
  • a clean light border next to a darker background
  • a border edge that is easy to separate from the interior image

If the border and artwork are very close in tone, very noisy, or washed out, the hint may be weaker or may not appear.

Best way to use it:

  • drag the guide close by eye first
  • zoom in for a better final check
  • watch the loupe for the suggested edge assist
  • if it looks correct, use it to fine-tune the guide

If the hint looks wrong, ignore it and keep aligning manually. Your eye should still make the final call.

What Do View Mode and Exposure Do?

View Mode changes how the card picture is displayed to make edges easier to see. Try Brighten + Contrast or Border Assist when the border is hard to line up in the original image, and try Low-Res when you want a simplified lo-res view that reduces fine noise and makes broader border regions easier to spot. Use Exposure if the photo is too dark or too bright.

These display controls only help visibility. They do not change the actual guide measurements.

Estimated Centering Grades

The Results panel also shows estimated centering-only grades for PSA, BGS, TAG, and CGC. These are meant as quick reference points based on published centering thresholds, not full grading predictions.

The estimate uses the worse of the two axes, so if left/right and top/bottom do not land in the same bucket, the lower centering result wins. Front and back are shown separately because grading companies use different thresholds for each side.
